We are using Maximizer v5.1 SQL, One of our biggest problems, is that the 'must match all' search criteria does not work with our core user defined fields. When we select the criteria 'Must Match All' when doing a search and then select our UDF or multiple UDFs, even though there is definately data assigned to the UDF. The result returns no data whatsoever. We have tried to reverse engineer the TSQL to find out exactly what this flag references but to no avail. We have also spoken with Multiactive to get them to reopen the code, also to no avail.. Can anyone help ?
